It happened again: you reach for a can of Old Milwaukee only to feel that tell-tale bulge at the top of the can. The beer froze… again. D’OH!
The problem is usually the damper door assembly— these have been a real cash cow, er, I mean, headache for servicers since dayo uno.
What usually happens is that the damper door cracks and gets stuck in the wide open position. Look in there and see. If this is what’s happened to yours, then you’ll need to replace the entire damper assembly.
